IIS/ASP Performance Issue. RRS feed

  • Question

  • Hello Sir,

    We are going through the slowness problem with the website nowadays. Sometime web site is working fine and sometime suddenly we are getting 
    errors Sys.WebForms errors on users screen, slow responses, time outs from the database end. Can you please advise use how do we find bottlenecks for this? What tools or methods will help us to determine the issue here.

    We have .NET 2.0 Application hosted across 4 web server and pointing to SQL Server 2005 database with SQLState Session, We are also using loadbalancer with some SSL validation so one server will have user limit to 200, second with 200, third with 50 and fourth with 50. We have average 200 rows comes back when we do 'sp_who2' with the database. We also have setup 200 connection pool size from each web server in web.config. We have average 300 users per seconds on our web site overall. We are also doing SQL Replication on other server.
